The main problems you will see with the servo cutter are:

DANGER: Sharp blades!

Most injuries caused by knife blades occur when the cutter has been turned off. Handle blades with care at all times.

●Always wear cut-resistant gloves when the cutting chamber is open and when handling blades.

●Always lock out power to the cutter before opening the cutting chamber.

●Always wait until the cutter head has stopped completely before opening the knife guard.

SC-5 Sure Cut cutters are equipped with several safety devices to ensure safe operation. Never remove or disable these devices to sustain pro- duction. Operating without these devices can cause severe injury.

●When the knife guard is opened, the knife guard switch stops the cutter and prevents starting the cutter again.

●Two proximity-type safety switches prevent operation unless the cutter bushings are in place.

●The STOP button activates a circuit that stops the knife.

A FEW WORDS OF CAUTION

CONTINUED

The Troubleshooting section covers problems directly related to the operation and maintenance of the servo cutter. This sec- tion does not provide solutions to problems that originate with other equipment. Additional troubleshooting help can be found in manuals supplied with the other equipment.

The main problems you will see with the servo cutter are:

●Cutter operation problems, which focus on problems that are clearly related to the operation of the cutter’s electrical control systems.

●Plastic product quality concerns, which deal with prod- uct characteristics that may be related to cutter operation. Of course, other sections of the extrusion line also influ- ence the quality of the extruded product. This section does not provide solutions to problems originating with other equipment on the extrusion line.

Additional troubleshooting help can be found in the manufac- turer’s manuals included with this User Guide.
